VR4G63 Posted July 18, 2022 Report Share Posted July 18, 2022 Hi Team, I'm currently looking to add a surge tank to car with another x 2 surge tank fuel pumps. Looking to use existing fuel pump trigger for lift pump and x 1 surge tank pump. As for the extra pump was thinking about wiring it into to ecu to start once it sees a certain DC % as a GP output. Question: can I use Aux 2 ( egr ) as GP output to control second fuel pump ? Currently using pin 62 & pin 65 for fan control would pin 53 aux 2 be suited for this. Thanks in advance Quote Link to comment Share on other sites More sharing options...
